Thanks, folks. Great suggestions. Now to figure out which way to go.

The AODE is the cheapest and least intrusive and directly displays
battery voltage and total charge or discharge Amp-hours, like a
battery fuel gauge.

The TP4000 DVM can also measure temperature with a fairly thin
thermocouple that won't cause much heat loss where it goes into the
fridge under the door gasket, though I used a fine wire thermocouple
from Omega to record how my refrigerator cycles.

The program that came with mine allows up to four separate
installations assigned to COM1 through COM4.
